29. The Beatles, 'Help!'

"Most people think it's just a fast rock & roll song," Lennon said. "Subconsciously, I was crying out for help. I didn't realize it at the time; I just wrote the song because I was commissioned to write it for the movie." Overwhelmed by Beatlemania, Lennon was eating "like a pig," drinking too much and "smoking marijuana for breakfast" — only 24 years old, he was already expressing nostalgia for his lost youth. "I don't like the recording that much," Lennon would later tell Rolling Stone. "We did it too fast, to try and be commercial."
